16.0 grams of food contain 130 calories. How many grams of food would you need in order to consume 2150 calories?
Answer:
you can set up a proportion
16.0/130 = x/2150
by cross multiplying you get
130x = 34400
divide by 130 and get
x-264.62
A set of weights includes a 4 lb barbell and 6 pairs of weight plates. Each pair of plates weighs 20 lb. If x pairs of plates are added to the barbell, the total weight of the barbell and plates in pounds can be represented by f(x) = 20x + 4.
Answer:
Range[4,24,44,64,84,104,124]
Step-by-step explanation:
CHECK THE COMPLETE QUESTION BELOW;
A set of weights includes a 4 lb barbell and 6 pairs of weight plates. Each pair of plates weighs
20 lb. If x pairs of plates are added to the barbell, the total weight of the barbell and plates in
pounds can be represented by f x( ) = 20x + 4.
What is the range of the function for this situation?
The range of a function can be defined as the difference between the maximum and minimum function. From the question, we can deduced that the minimum function of X is 0 and no plate is added, and the maximum is 6
The given function is
f(x) = 20x + 4 =
f(0) = 20(0) + 4
= 4
f(6) = 20(6) + 4
= 124
Which means the range is within 4 and 124.
But we are told from the question that Each pair of plates weighs 20 lb, which means there is difference of 20ib each between 4 and 24
Then we can compute the range as [4,124] or (4,24,44,64,84,104,124)
A recipe for blueberry muffins states that it yields 12 muffins, with 270 calories per muffin. You instead decide to make
mini-muffins, and the recipe yields 20 mini-muffins. If you eat 7 mini-muffins, how many calories will you consume?
Answer:
The calories you will consume are 1134 calories
Step-by-step explanation:
Let us solve the problem
∵ A recipe for blueberry muffins states that it yields 12 muffins, with 270
calories per muffin
→ Find the total calories of the 12 muffins
∴ The total calories of them = 12 × 270
∴ The total calories of them = 3240 calories
∵ You instead decide to make mini-muffins, and the recipe yields 20
mini-muffins
→ That means the same amount of calories are in 20 mini-muffins, to find
the calories of each one divide the total amount of calories by 20
∵ The calories per mini-muffin = 3240 ÷ 20
∴ The calories per mini-muffin = 162 calories
∵ You will eat 7 mini-muffins
∴ The calories you consume = 7 × 162
∴ The calories you will consume = 1134 calories
Tickets to the zoo cost $12 for adults and $8 for children. The school has a budget of $240 for the field trip. An equation representing the budget for the trip is 240=12x+8y. Here is a graph of this equation:
Answer:
18 children
Step-by-step explanation:
Given
[tex]240 = 12x +8y[/tex]
Required (missing part of the question):
Number of children that will be able to go to the zoo if 8 adult tickets are purchased
The graph is missing. However, the question can be solved without the graph.
From the question and equation, we can deduce the following:
x represents adultsy represents childrenSo, when 8 adult tickets were sold.
This means
[tex]x = 8[/tex]
Substitute 8 for x in [tex]240 = 12x +8y[/tex]
[tex]240= 12 * 8 + 8y[/tex]
[tex]240= 96+ 8y[/tex]
Subtract 96 from both sides
[tex]240 - 96 = 96 - 96 + 8y[/tex]
[tex]144 = 8y[/tex]
[tex]8y = 144[/tex]
Solve for y
[tex]y= \frac{144}{8}[/tex]
[tex]y= 18[/tex]
This means that 18 children will be able to go

A rocket booster initially applies 10,000 N of force to a 1,000.0 kg rocket causing it to accelerate at 10.0 m/s2. Ten minutes later, the rocket booster is released and it falls through the atmosphere.
The mass of the rocket is now 760.0 kg and its acceleration is 7.0 m/s2. How much force is now being applied to the rocket?
Answer:
5320 Newtons
Step-by-step explanation:
mass time acceleration so 760 kg times 7 secs
The force that should be applied to the rocket is 5,320N.
Given that,
The mass of the rocket is now 760.0 kg and its acceleration is 7.0 [tex]m/s^2.[/tex]Based on the above information, the calculation is as follows:
[tex]= 760 \times 7.0[/tex]
= 5,320N

Multiply using the distributive property (X+4)(X^2+6x-3)
Answer:
x^3 + 10x^2 + 21x - 12
Step-by-step explanation:
(x + 4)(x^2 + 6x - 3)
you can separate to make it easier for u
x(x^2 + 6x - 3) + 4(x^2 + 6x - 3), this is optional u don't have to do this part
x^3 + 6x^2 - 3x + 4x^2 + 24x - 12
add like terms together
x^3 + 10x^2 + 21x - 12
A ball is thrown from the top row of seats in a stadium. The function h(t)=-16t2+48t+160 gives the height, t, in feet, of the ball t seconds after it is thrown. How long will it be before the ball hits the ground?
Answer:
t = 5 s
Step-by-step explanation:
The function that gives the height in feet of the ball t seconds after it is thrown is :
[tex]h(t)=-16t^2+48t+160[/tex]
We need to find how long will it be before the ball hits the ground. When it hits the ground, its height will be equal to 0.
So,
[tex]-16t^2+48t+160=0[/tex]
We need to solve this equation. When we solve, we get its solution as shown in the figure. We can see that t = -2 s and t = 5 s.
t = -2 s is not possible.
Hence, the ball will hit the ground before 5 seconds.

Answer:
5128 2/3 m³
Step-by-step explanation:
Cone Volume Formula: πr²h/3
3.14(14²) * 25/3
3.14(196) * 25/3
615.44 * 25/3

GCD = 75
46158/75 * 625/75
46158/3 * 25/75
15386/3 * 25/25
15386/3
5128 2/3 m³ is the volume.
